PROCESS FOR MAKING BAG-FRAMES.

Original application filed May 9, 1910, Serial No. 560,163.

Specification of Letters Patent.

Serial No. 589,122.

To (zZZ whom it may concern:

Be itknown that I, FRANZ A. FULLER, a citizen of the United States,residing in the city of Newark, in the county of Essex and State of NewJersey, have invented a certain new and useful Process for MakingBag-Frames, being part of the original ap plication, filed May 9, 1910,Serial No. 560,163, for improvements in bag-frames; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make, construct, and use the same, reference being had tothe accompanying drawings, and to letters of reference marked thereon,which form a part of this specification.

This invention has reference to improvements in the manufacture offrames for bags and purses, especially for traveling, chatelaine andsimilar bags.

The object of my invention is to overcome present difiicultiesdispensing with the numerous constructions heretofore employed forconnecting the pivot members with the main body of the frame section, inorder to produce a bag frame with sharp angular corners, by making aframe from one piece of material, thereby producing a neat, sharp andsolid corner angle, free from open joints, and one in which the crackingor puckering of the metal at the corners of the frame during the processof the manufacture of the same, is entirely overcome.

In the accompanying drawings forming a part of this specification,Figure l illustrates the blank which subsequently forms the bag framemember, preparatory to channeling the member and makin the bend to formthe square corner. Fig. 21llustrates the blank after being channeled andthe method of bending the channeled blank member to form the squarecorner. Fig. 3 represents a plan view of the same. Fig. 4 illustrates afront elevation of a bag frame; and Fig. 5 is a cross-section of thesame.

Similar letters of reference refer to like parts throughout thespecification and drawings.

In describing the process forming my invention, I will simultaneouslydescribe the product of the same, so that those skilled in the art towhich it pertains, may gain a full knowledge of the product, as well asof the process.

In Fig. 1, I have shown a sheet metal blank (4 as it is punched out. Theblank a comprises a main body portion provided at its extremities withears I). To complete the frame members 0, c with sharp corners, theblank a is first placed in a suitable die and the central portions ofthe blank (4 are channeled along the dotted lines as shown in Fig. 1, sothat a cross-section is, as shown in Fig. 5, and a side elevation is, asshown in F 2. It will be seen from an inspection of Fig. 2, that theblank when channeled as described is also simultaneously formed with thecusps (Z, (Z on the upper side and the notches e, c on the opposite orunder side. After the blank a is channeled, and provided with the cuspsand notches, as heretofore described, the hinge members f, f are bent atright angles to the main body member f, as illustrated in Fig. 2. Thecusps d, (Z will be found to contain a sufficient amount of material tostretch around the angle of the bend without weakening the same, andform a sharp and square corner which is so much to be desired in bagframes of the character to which my bag frame relates. At the same time,the notches 6 upon the opposite under side of the blank are of suchshape and dimensions, so as not to pucker or form ridges during theprocess just described. If it is attempted to bend a straight piece ofma terial, such as bag frames are usually made from, itwill be foundthat the inner corner will be puckered and covered with ridges, whilethe outer edge will be found to have stretched to such an extent as toappear ragged and present a cracked and unsightly appearance.

By the process described, I am enabled to produce a bag frame memberwhich is composed of a single piece of metal, and without the usual openjoints and angled connections, and yet, by the exercise of this process,I am able to produce the frame with a minimum of waste material, and atthe same time preserve maximum strength at the hitherto weakened pointsin the frame.

I claim 1. The process of forming channeled sheet metal bag framesconsisting in forming a flat sheet metal blank bending said blanktransversely to form a channeled member U-shaped in cross section,forming said channeled member with notches in the edges of the sidewalls thereof, and with cusps projecting from the top wall thereof andbending the channeled member at the notches in the side walls thereof toform the hinge members of the bag frame.

2. The process of forming sheet metal bag frames consisting in forming aflat sheet metal blank channeling the central portion of said blanklongitudinally and simultaneously forming cusps projecting from theupper blank and notches adjacent said cusps in the edges of the sidewalls of the channeled portions of the blank, and bending the blank atthe notched portions thereof to form a completed member with sharpcorners.

This specification signed and witnessed this 20th day of October, 1910.
